DPS310XTSA1

DPS310XTSA1 is a Digital XENSIV™ miniaturized digital barometric air pressure sensor with high accuracy and low current consumption, capable of measuring both pressure and temperature. The pressure sensor element is based on a capacitive sensing principle which guarantees high precision during temperature changes. The small package makes the DPS310 ideal for mobile applications and wearable devices. The internal signal processor converts the output from the pressure and temperature sensor elements to 24bit results. Each unit is individually calibrated, and the calibration coefficients calculated during this process are stored in the calibration registers. The coefficients are used in the application to convert the measurement results to high-accuracy pressure and temperature values. The application includes indoor navigation, health and sports, outdoor navigation, weather station, HDD drivers, and drivers.
